It wasn't until Friday -- the day Trump signed the order banning travel from seven Muslim-majority countries for 90 days and suspending all refugee admission for 120 days -- that career homeland security staff were allowed to see the final details of the order, a person familiar with the matter said.
The result was widespread confusion across the country on Saturday as airports struggled to adjust to the new directives. In New York, two Iraqi nationals sued the federal government after they were detained at John F. Kennedy International Airport, and 10 others were detained as well.

In Philadelphia, a Syrian family of six who had a visa through a family connection in the US was placed on a return flight to Doha, Qatar, and Department of Homeland Security officials said others who were in the air would be detained upon arrival and put back on a plane to their home country.
Asked during a photo opportunity in the Oval Office Saturday afternoon about the rollout, Trump said his government was "totally prepared."
"It's working out very nicely," Trump told reporters.
